What is Newton's Second Law, and Third?
Newton's Second Law of Motion:
Newton's second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically, this law can be expressed as:
F = m * a
Where F represents the net force applied to an object, m represents the mass of the object, and a represents the acceleration produced by the force. This law essentially explains how the motion of an object changes when it is subjected to an external force.
Newton's Third Law of Motion:
Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force on the first object. In simpler terms, it implies that forces always come in pairs. For example, when you push a wall, the wall pushes back on you with an equal amount of force. This law helps to explain interactions between objects and is a fundamental concept in physics.
